This web page contains a collection of articles written by me, and published in Sky and Telescope magazine, Astronomy magazine, and others. Virtually all of the questions that you may have about cosmology can be answered by reading one or another of these essays. I will eventually provide links to these essays so you can easily read these basic articles in cosmology. Meanwhile, several of my blog essays cover these topics too!
Books:
Patterns in the Void:Why nothing is important, is now out-of-print and explained some of the exciting, and troubling, aspects of modern cosmology.
My new book Exploring Quantum Space explains why space is far more mysterious than being just a container of things.
Popular Science Articles (1983 – 2007):
These essays were originally published as feature articles in magazines and newspapers between 1984 and 2007 and are a bit out of date by now, so I have updated them as new blog essays to make them more readable and current!
